Rupes Altai and Rothmann Zagut Sacrobosco craters.

There are many craters in these images can be highlighted: Rothmann (42 km) Lindenau (53 km), Zagut (84 km) and Sacrobosco (98 km), of which are just larger in size. All of them are located on the left of Rupes Altai which is the second outer collar surrounding Mare Nectaris basin.

Zagut crater is interesting because it contains another crater on the east floor named Zagut E (35 km) which alter the shape of Zagut. Near the center is found a small crater, Zagut A (11 km).
Sacrobosco with 3 craters on the floor A (17 km), B (14 km) and C (13 km) located in the triangle are also features that captivates your attention.

In the picture below are labeled craters and other lunar features in the region. To better understand this photo, you should note that the label with the name or the letter of larger craters could be found at their center, and on the small craters, you should find them around them, usually above.

Moon craters - astronomy pictures through telescope

All these pictures are made on 09.02.2011 and I decided to post all of them in a single article

Piccolomini crater (88 km.) in the center pf the photo,and Rupes Altai is the rim that goes down below the crater.(photo above and below)

Apianus G is in the center.Above Apianus G, on right is Apianus (63 km),and on left is Playfair (48 km.)

Aliacensis (80 km.) is on the right of picture,and Werner (70 km.) below it.

Aristoteles (87 km.)-the bigest one, and Euxodus (67 km.)-below.

Hommel and Pitiscus craters-are on center-lower of the photo above

Craters aligned from left to right: Rheita E (the elonged one),Rheita(70 km.),Metius (88 km.) and Fabricius (78 km.)

Crater Janssen (190 km.)-the big one on the left-down,Vlacq (89 km.) and Rosenberger (96 km.) on right

The two craters combined in the center are Watt (66 km.) and Steinheil (67 km.) below it.

Barocius (82 km.) on right-center.Under, is in shadow, Maurolycus (114 km.)

Rupes Altai is the mountain chain-up from left to right.On the right in photo is Zagut (84 km.)

Dalambre Crater (52 km.) which is in the center, beneath is Taylor A and Taylor (41x34 km.)

On the Mare Tranquillitatis are Plinius crater (43 km.) is in left-center, Ross (26 km.) south-east of Plinus, and Arago at the bottom left.

Astronomy through the telescope. Craters south of Rupes Altai.

Rupes Altai is actually a portion of a ring surrounding the Mare Nectaris basin. This large ring disruptions continue its route, if we imagine a continuous line around the basin. Incidentally, the Rupes Altai, is a portion of the ring without being interrupted, within a radius of 427 km. These multiple rings were formed due to the major impact that formed the basin.

In these images, Rupes Altai chain, is in the sunlight shining from a high angle, so the area is in light, which is reflected by the sun.

Craters visible in these images: Rothmann G, C, Pons (41 km), Zagut (84 km), A (11 km), E (35 km), Polybius (41 km), Wilkins (57 km) and Celsius (36 km).

List of east features of the Moon. astronomy lecture

East of the Moon is marked by several interesting features. Most notably is Mare Crisium, a "sea" visible from the Earth with the naked eye as an isolated spot by other seas, dark in colour.
 Notable craters on the east side of the Moon are Posidonius, Petavius ​​and Langrenus, which are the largest in size.
 Even if it seems that East of the Moon has not too many huge craters, actually there are many  small craters as we can see in the list below.

Space missions on the east side of the Moon.

Apollo 16 (1972) with people on board. Apollo 16 was the tenth mission in the Apollo program with humans. It was launched on 16 April 1972 and ended on 27 April. It was a lunar rover mission and brought back 94.7 kg of lunar soil and rock samples.

Apollo 17 with people on board. EVA activity (EVA). Apollo 17 was the 11th and last  manned mission of the Apollo space program. Launched at 12:33 a.m. on 7 December 1972, with a crew of three members: Eugene Cernan, Ronald Evans and Harrison Schmitt. Apollo 17 landing remains the most recent made ​​beyond Earth's orbit.

 Luna 21 (1973) USSR (Union of Soviet Socialist Republics), has successfully carried on the lunar surface rover Lunakhod 2 on January 15, 1973. It sent back 86 panoramic images and over 80,000 TV pictures.

Ranger 8 (1965) USA - intentionally crashed. Launched on February 20, 1965. Ranger 8 successfully sent 7137 images with a resolution of up to 1.5 m.

Surveyor 5 (1967) successfully landed. It sent more than 19,000 images to Earth, and has conducted more than 100 hours of compositional analysis of the surface.
